Abnormally high tire pressure (tread worn in center)
HSB013AA
Ride comfort is poor. Also, the tire magnifies the effects of road-sur-
face bumps and dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for the vehicle when fully loaded
and for the vehicle when towing a trailer, adjust the tire pressures to the
values that match current loading conditions.
WARNING
Driving at high speeds with excessively low tire pressures can
cause the tires to deform severely and to rapidly become hot. Asharp increase in temperature could cause tread separation, and
destruction of the tires. The resulting loss of vehicle controlcould lead to an accident.
Wheel balance
Each wheel was correctly balanced when your vehicle was new, but the
wheels will become unbalanced as the tires become worn during use.
Wheel imbalance causes the steering wheel to vibrate slightly at certain
vehicle speeds and detracts from the vehicle ’s straight-line stability. It
can also cause steering and suspension system problems and abnormal
tire wear. If you suspect that the wheels are not correctly balanced, have
them checked and adjusted by your SUBARU dealer. Also have them
adjusted after tire repairs and after tire rotation.

NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the vehicle
’s running stability. Contact your
SUBARU dealer if you notice abnormal tire wear.
* : The suspension system is designed to hold each wheel at a certain alignment
(relative to the other wheels and to the road) for optimum straight-line stability and
cornering performance. Wear indicators
Each tire incorporates a tread wear indicator, which becomes visible
when the depth of the tread grooves decreases to 0.063 in. (1.6 mm). A
tire must be replaced when the tread wear indicator appears as a solid
band across the tread.

WARNING
When a tire ’s tread wear indicator becomes visible, the tire is
worn beyond the acceptable limit and must be replaced immedi-
ately. With a tire in this condition, driving at high speeds in wetweather can cause the vehicle to hydroplane. The resulting lossof vehicle control can lead to an accident.
NOTE
For safety, inspect the tire tread regularly and replace the tires be- fore their tread wear indicators become visible. A) New tread
B) Worn tread
